  • What are signs that my cooling or heating system is not working?

    If your system is making strange noises, not providing enough cooling/heating, taking longer than usual to heat/cool, or if you noticed a sharp rise in your utility bills for no reason, then you may need to have your unit looked at by a professional.
  • How often should I have maintenance done on my A/C or heater?

    Maintenance should be done at least annually to ensure that your system is performing efficiently. Regular checkups and tune-ups can also maintain the longevity of your unit help to avoid costly repairs or replacements in the future.

  • How can I improve my indoor air quality?

    You can install a filtration device or a humidifier to maintain a healthy level of humidity and minimize pollutants. It is also important to perform regular maintenance on humidifiers and change your air filters regularly. We can have a technician come to your home to test your air quality and make recommendations on filtration systems or humidifiers.
  • How do I choose an energy-efficient A/C or heater?

    We recommend that you look for the ENERGY STAR® label, which indicates that the product has met stringent energy efficiency standards set by the government.
  • What size heating/cooling unit should I choose?

    When choosing an air conditioner or heater, it is important to measure the space to ensure that it will sufficiently cool or heat your home efficiently. Other factors to consider include how much sun or shade covers your living space, the size of your family, and the location of the unit. A certified technician from our team can come to your home, measure your space, and provide a recommendation based on your family's needs and budget.
  • How can I lower my utility bills?

    Some simple tips to save on energy bills include improving insulation by sealing windows/leaks, cutting back on water usage, replacing light bulbs, turning off appliances/lights when not in use, and performing regular maintenance on your heating/cooling systems.
